Quzhou Lei's medical pediatrics inherits Qian Yi's academic ideas,while combining Quzhou's lo-cal characteristics and schools of thought,and develops the concept of pediatric differentiation and treatment through works such as"Treatise on Seasonal Diseases".The following viewpoints are proposed:children belong to tender yin and tender yang,and attention should be paid to nourishing yin and protecting yang,as well as caring for children's spleen and stomach during treatment.On the basis of valuing observation and examination,emphasis is placed on ex-amining children's facial complexion,and on this basis,a combination of four diagnostic methods is carried out.Pre-scriptions from ancient and modern times should be applied through chemical methods,while also emphasizing the use of medicinal references and the selection of water for decocting.For the diagnosis and treatment of pediatric spleen and stomach,it is necessary to balance the spleen and stomach during the acute phase,and pay attention to regulating the spleen and stomach during the chronic treatment phase,and achieve lung spleen coordination.In addi-tion to being light,flexible,and specialized in medication,it is necessary to regularly regulate the children's heart and liver andpay attention to the emotional state of children during diagnosis and treatment.It's advocated that care should be in accordance with the four seasons.The above viewpoints not only enrich the theoretical connotation of traditional Chinese medicine pediatrics,but also achieve good therapeutic effects in clinical practice based on the developed theories,which is worth further exploration and promotion in the future.
